Abstract
This study compares the draft requirements of a shallow leading tine ripper, (shallow tines attached ahead of the deep tines that rip the soil to the intended depth) with a conventional ripper (single tine). The results show that attaching a shallow leading tine ahead and in-line with the main tine and at about one third to one half of the depth of the main tine produces the largest significant decrease in draft force (up to 17.7%). Attaching more than one shallow leading tine ahead of the main tine either (a) increases the draft force when offset; or (b) decreases it insignificantly when in-line with the main tine. The advantages of the shallow leading tine ripper over the conventional (single tine) ripper, besides requiring significantly less draft force are: (i) improved soil tilth (smaller aggregate clod sizes); (ii) a wider range of soil moisture conditions and therefore increased time over which effective ripping can be done ; and (iii) less wear on tines and points.
